(Sharecast News) - Asia-Pacific markets mostly declined on Tuesday as investors reacted to South Korea's August inflation rate, which dropped to the lowest annual level since March 2021.

Wall Street was closed on Monday for the Labor Day holiday, giving the Asian session less of an overnight catalyst, as investors looked to the US non-farm payrolls report due later in the week.

"North American investors return from the long weekend holiday to a less-than-welcoming market, stepping into a seasonally gloomy tunnel with the year's most crucial jobs report looming large," said SPI Asset Management managing partner Stephen Innes.

"This report is set to draft the Fed's policy script for 2024, and everyone's hoping for a steady state affair with the numbers landing squarely in the Goldilocks zone."

Innes said the pressure around the report was "even more intense" this time, thanks to a larger-than-expected negative revision to payroll data for the 12 months through March.

"This revision has only upped the ante, making it all the more critical for this jobs report to come in strong.

"In China, the story remains as predictable as ever: the economy desperately needs a jolt of big-ticket fiscal stimulus aimed directly at households to kickstart spending.

"The lack of demand is glaring, and simply tinkering with the supply side of credit won't cut it."

South Korea inflation slows to 42-month low

On the economic front, South Korea's inflation rate in August slowed to its lowest annual level since March 2021, with the consumer price index (CPI) rising 2% year-on-year.

That marked a decrease from July's 2.6% increase, and aligned with economists' forecasts, according to a Reuters poll.

On a monthly basis, the CPI edged up by 0.4%, slightly above the 0.3% increase that analysts had anticipated.
